TO ALL WHOM IT MAY CONCERN:

Be it known that we, JACOB SPOONHOUR, of Green township, Franklin county, Pennsylvania., and SAMUEL Rl BOYD, of the borough of Chambersburg,-in said county of Franklin, have invented a new and useful Improvement to Bridle-Bits; and we do hereby declare that the following is a full andA exact description thereof, rcfer-.

ence being had lto the accompanying drawings, and to the letters ofreference marked thereon.

We dsclaim,'as our invention, every part of the bridle-bit, (a drawing of which accompanies this-application,) and make no claim that any part of the same is new, except as hereinafter specified. t

The nature of our invention or improvement is' this; We take any of the known forms of bridle-bits now in use, and we attach to such bit, by clip, rivet, or otherwise, an elliptical-shaped side piece, marked A, (see drawing accompanying the application.) This side piece may. be so arranged as to be stationary, and immovably i fix'ed to the bit, or it may be so arranged as to' swing on the bit. To this side piece a clasp or bearing, marked B, (sce accompanying drawing,) is attached, furnish-ed with a roller, marked C, (reference being had to thedrawing.) The roller is fastened and held in its place, inside of the clasp or bearing, by a screw, marked D,

see accom an in drawinv, 'or it can be fastened and held b a rivet or otherwise. An 'of the known forms P y g o Y n y of driving-rings, designated on the accompanying drawing by the letter E, may be attached to the clasp or bearing, and to this ring the driving-line or rein, in any of the now known forms, is fastened. V

To enablelothers skilled in the manufacture of bridle-bits .to make and use our improvement thereto, we will proceed to describe its operation.

It consists in this: When the horse presses upon the bit, thebearing or clasp revolves on its roller, along the elliptical-Shaped side piece, and shifting downwards from the-centre of the bit,- cerises the bit to turnrin the horses mouth, forcing it open, according tothe amount of pressure exerted on the`bit.

What we claim as our invention, and desire to secure by Letters Patent, is l The elliptical-shaped side piece, marked A, the clasp or bearing, marked B, the rollen-,marked 0,'aml the screw Or rivet, marked D, as represented on the accompanying drawing, and hereinbefore explained and set forth.
